|Gasification of Municipal Solid Waste for Large-Scale Electricity/Heat||
Thermal gasification of municipal solid waste (MSW) is a chemical process that generates a gaseous, fuel-rich product. This product can then be combusted in a boiler, producing steam for power generation. Just as with combustion of MSW, thermal MSW gasification does not necessarily compete with recycling programmes, but should be considered complementary in any generically constructed MSW plan.
|Geothermal Electricity Production||
Inside the Earth's crust there are several reservoirs with hot water which can be used for heating buildings and/or production of electricity. The process causes relatively little CO2 emissions (from the steam), which could potentially be reinjected in the earth's crust through carbon capture and storage. Contrary to conventional geothermal power plants, present generation plants re-inject the condensated steam or hot water into the underground acquifer so that the reservoir capacity could remain intact.
